Hi I wan' t to convert my DVD, Dvix and MKV in mp4 file to wath them with the new Apple TV. For do that I use Handbrake but I don' t know what are the best settings to have a lossless convertion. If i use "high profile" preset the "constant bitrate" oprion is set to 60%. I must use 100% to have a lossless convertion? thanks!
